Isingeniso
I-amplifier yomsindo iyithuluzi elakha kabusha isignali yomsindo efakiwe kusici esikhiphayo esikhiqiza umsindo, futhi umthamo wesignali owumphumela nesiteji samandla kuhle—kuyiqiniso, kuyasebenza, nokuhlanekezela okuphansi.Ibanga lomsindo licishe libe ngu-20Hz ukuya ku-20000Hz, ngakho-ke isikhulisi kufanele sibe nokusabela okuhle kwefrikhwensi ngaphakathi kwalolu bubanzi (okuncane uma ushayela izipikha ezine-band-constrained, ezifana nama-woofer noma ama-tweeter).Ngokuya ngohlelo lokusebenza, usayizi wamandla uyahluka kakhulu, ukusuka kuma-milliwatt wama-headphones kuye kuma-watt amaningana omsindo we-TV noma we-PC, kuya kumawathi amaningi esitiriyo sasekhaya "esincane" nomsindo wemoto, kuze kufike kumakhulu ama-watts anamandla kakhulu asekhaya nakwezentengiso. amasistimu omsindo, amakhulu ngokwanele ukuhlangabezana nezidingo zomsindo wesinema yonke noma ihholo.
Ama-amplifiers omsindo angenye yezingxenye ezibalulekile zemikhiqizo ye-multimedia futhi asetshenziswa kabanzi emkhakheni we-electronics yabathengi.Izikhulisamsindo zolayini bezilokhu zihamba phambili emakethe yesikhulisamsindo yendabuko ngenxa yokuhlanekezela kwazo okuncane kanye nekhwalithi yomsindo enhle.Eminyakeni yamuva nje, ngokuduma kwemishini yemultimedia ephathekayo efana neMP3, PDA, omakhalekhukhwini, namakhompyutha ezincwadi zokubhalela, ukusebenza kahle kanye nomthamo wezikhulisamandla zomugqa awusakwazi ukuhlangabezana nezidingo zemakethe, futhi izikhulisamandla zamandla ekilasi D ziya ngokuya zithandwa. ngabantu abanezinzuzo zabo zokusebenza kahle kanye nosayizi omncane.Ngakho-ke, ama-amplifiers e-Class D asebenza kahle anenani lesicelo elibaluleke kakhulu kanye namathemba emakethe.
Ukuthuthukiswa kwezikhulisi zomsindo sekudlule ezinkathini ezintathu: amashubhu e-electron (amashubhu e-vacuum), ama-bipolar transistors, nama-transistors asebenza ensimini.Isikhulisi somsindo weshubhu sinethoni eyindilinga, kodwa sikhulu, sisetshenziswa amandla aphezulu, ukusebenza okungazinzile ngokwedlulele, nokusabela okungekuhle kwefrikhwensi ephezulu;I-Bipolar transistor audio amplifier frequency bandwidth, ububanzi obuguquguqukayo obukhulu, ukwethembeka okuphezulu, impilo ende, kanye nokuphendula okuhle kwemvamisa ephezulu, kodwa ukusetshenziswa kwayo kwamandla amile, ukumelana nokumelana kukhulu kakhulu, ukusebenza kahle kunzima ukuthuthukisa;Ama-amplifiers omsindo we-FET anethoni eyindingilizi efanayo njengamashubhu, ububanzi obuguquguqukayo, futhi okubaluleke nakakhulu, ukumelana okuncane okungafinyelela ukusebenza kahle okuphezulu.
Ukubunjwa Kwesakhiwo
Injongo yokukhulisa umsindo iwukukhiqiza kabusha isignali yokufaka yomsindo ngevolumu edingekayo kanye neleveli yamandla kusici esikhipha umsindo ngokusebenza kahle okuphezulu nokuhlanekezela okuphansi.Ububanzi befrikhwensi yesiginali yomsindo ngu-20Hz ukuya ku-20000Hz, ngakho-ke isikhulisi somsindo kufanele sibe nokusabela okuhle kwefrikhwensi.Izikhulisa-msindo ngokuvamile zihlanganisa i-preamplifier kanye ne-amplifier yamandla.
I-Preamplifier
I-amplitude yesiginali yomthombo wesignali yomsindo ngokuvamile incane kakhulu futhi ayikwazi ukushayela ngokuqondile isikhulisi samandla, ngakho kufanele siqale sikhuliswe sibe yi-amplitude ethile, edinga ukusetshenziswa kwe-preamplifier.Ngokungeziwe ekukhuliseni isignali, i-preamplifier ingaba nemisebenzi efana nokulungiswa kwevolumu, isilawuli sephimbo, isilawuli somsindo omkhulu, nokulingana kwesiteshi.
Isikhulisi samandla
Izikhulisi zamandla zibizwa ngokuthi izikhulisamandla, futhi inhloso yazo ukuhlinzeka ngekhono elanele lokushayela lamanje emthwalweni ukuze kuzuzwe ukukhuliswa kwamandla.I-amplifier ye-Class D isebenza esimweni sokushintsha, ngokwethiyori ayidingi i-current ethule, futhi isebenza kahle kakhulu.
